Lette/r3 Patent No. 100,363, dated March 1, 1870.

IMPROVEMENT IN WOOD PAVEMENT.

The Schedule referred to in these Letters Patent and making part 0f the same.

To all whom. 'it may concern:

Be it known that I, L. H. BooLn, ofthe city of N ew York, and State of New York, have invented a new and useful Water-Proof Pavement and I do hereby declare the following to be an exact .descliption thereof, reference being had to the accompany'- ing drawings and to the letters of reference marked thereon making a part of this specification, in which- Fignre 1 represents a top view ofthe pavement.

Figure 2 shows the blocks set in ra row, and resting upon two layers of boards or planks.

Figure shows how each row is tirmly tightened by means of key-blocks being inserted at suitable distances apart.

Figure 4 exhibits the openings between the rows` of blocks, having a tari-ed rope inserted.

The nature of my invention consists in au improved method of rendering wood pavement water-proof, by means of a rope pressed into grooves formed between the blocks, and in the combination of key-blocks and foundations therewith.

'The object of my invent-ion is to make a cheap pavement, free from noise, tirm, yet easier to travel upon than pavements of rammed stone or other stone foundations, at the same time water-proof, which increases its durability.

To enable others skilled in the art to make my invention I will proceed to describe its construction, as follows: Y

A represents the tops of the blocks that have been cnt to a given length, and set or laid (so as to break joints) in rows, ti'om curb to curb.

B exhibits the board or plank flooring, upon which the blocks are placed in rows, the boards beingilaid diagonally and tlat upon the ground, in one, two, or three layers or thicknesses, the upper layer crossing the lower one at right angles, so as to cross each other in a perfectly opposite '-direction, and diagonally with the line ofthe street. This makes a irxn and even foundation for the'blocks Ato rest uponfor when blocks have been placed upon boards laid crosswise or directlyv on a line with the street, the ends of the boards soon become out of place and tipped up or down. I

C shows the shape and construction of the wedgeshaped key-block, with its one lower side tapering, so as to correspond with the angular piece E that is placed at the side of one of the blocks A, that when the key-block is inserted and driven down to the ooring the pressure may be vequal and regular on bot-h sides of the key-block,

D D are the openings or sea'ms extending across the street, between each row of blocks A, in which tarred ropes F-are inserted, and the seams D above iilled up with Vtar and sand, that eectually prevent the water from settling between the blocks, and'prevent the blocks from rotting or working loose, thereby securing the durability of the pavement.

G represents the sidewalks.

After the street has been graded to its proper level, I construct my pavement, as follows: vBy laying a se ries of boards or planks, B, running diagonally across the street. Upon this I place another layer ot' boards or planks diagonally, but in opposite directions, as shown at fig. 1,and if necessary I may have two or more thicknesses, but two thicknesses l deem the best. The blocks A are then laid upon this flooring in rows from curb to curb, and the key-blocks C are inserted at suitable distances. In order to make the pavement perfectly water-proof, each back seam D is opened, and a tarred rope, F, is pressed in about twothirds of the distance down, and the opening left above the rope is filled up with tar and sand.

What l claim as my invention, and desire to -secure by Lettersl Patent, s-

l A pavement composed of the blocks A, formed as described and shown, and the rope F pressed into the groove D, with proper iilling, as and for the purposes set forth. -x

2. In combination with such a pavement, the key' blocks'C, as and for the purpose set forth.

3. In combination with a pavement thus rendered water-proof and wedged, the foundation made of diagonally laid double thicknesses of plank, as and for the purpose set forth.
